Does the producer of “Entourage” need a new entourage? The HBO show’s Doug Ellin posted a status update on Facebook asking his more than 3,000 friends yesterday: “Where can I watch the game and eat in NYC tonight?” Suggestions ranged from Jake’s Dilemma to the Empire Hotel Rooftop, Bounce and the Ainsworth. Fictional agent Ari Gold, of course, would dial some super sports lounge’s unlisted number to book a table for himself, Vincent Chase and company. But we hear high-flying Ellin wound up meeting pals, including Knicks guard Baron Davis, at hot spot Willow Road.
